If you’re having problems with your Mac that may be caused by problems with the macOS, Internet Recovery Mode can download a clean copy of OS X. The difference between Recovery Mode and Internet Recovery Mode So, following a proper, Apple created Internet Recovery system which means you can reinstall your operating system efficiently and with the smallest amount of data loss possible.
That does not mean you will never run into issues, however. You should definitely do a Ted Talk on it and how it applies to network troubleshooting.One of the great things about macOS is that it tends to be relatively stable. I'm sure the same happens to people working in the medical world and other professions where accurate troubleshooting and diagnostics are required. There has been a few airline crashes where the pilots fixated on some technical issue when it was not the real issue at all. Presumption of the problem often leads to problem fixation. Generic troubleshooting should always include:Ī brief but accurate description of the desired outcome.Ī brief but accurate description of the failure mode, including error codes.Ī list of any troubleshooting steps you have done, and what the results were.Īctual text/output of basics like ipconfig/ifconfig/whatever, pings/traceroutes to destinations by IP and by name.Īny things you can remember that may have recently changed. We generally try to be helpful, but when we suggest you can exclude certain things from your mindset as being the source of the problem, you might want to listen.because it's frustrating to tell someone "no, that can't be the problem, have you tried x?" and they simply talk/walk around you.

Someone drops in, convinced they know what their problem is, and demanding to know how to fix it. Troubleshooting is a process.not attempting to bend something to your will. It limits you to tunnel vision, desperately trying to fix something that may or may not be broken. What we learned here is that you should *never* presume what the problem is when it comes to data communications. Sonicwall has Minimum Segment Size settings for DoS protection but no Maximum Segment Size setting, apparently automatically setting it around the MTU setting.Īnyway, any consumer type router should handle this all for you, especially as long as you don't set it to block ICMP (which includes Path MTU discovery which allows the MTU for devices to be discovered automatically).Īs a followup (this isn't directed at you komatsu, but at anyone who reads this thread later on) Once we lowered the MTU to 1450 everything worked great. Some websites would load but most would not. Just this morning I had to help a customer lower the MTU on their Sonicwall firewall when they set it up for PPPoE, for some reason, even though the firewall config has a spot to enable fragmentation, it would not work unless it was lowered to below 1450. You *may* need to set it on the router/firewall. If you are using a router or firewall of any kind for your internet service, you *should not* set the MTU on your end user devices (PCs, laptops, phones etc). If you are plugging your internet service directly into your computer/laptop then you *might* need to manually lower your MTU to around 1450 or so to be safe (you can optimize it a bit manually but it really doesn't matter). Every modern operating system I have dealt with automatically implements that MTU change once you enable PPPoE. The trick with PPPoE is that it uses some additional payload on the Ethernet frame and therefor requires your device use a slightly lowered MTU or MSS (or both). It literally does not exist as far as they know. Once the traffic hits that first ISP router, the encapsulation is discarded as it is no longer useful, your traffic becomes just the same as any other IPv4/IPv6 traffic on the internet.įor your specific situation, Apple has no idea you use PPPoE to authenticate and encapsulate your connection to your ISP.
PPPoE is only implemented on the WAN interface of your edge device (firewall, router, whatever gateway device you use) and the encapsulation only exists on traffic between your edge device and the ISP 'aggregator' device (usually the first router in the path between your device and the internet in general).

ISPs use it to provision connections for customers/users with Username and Password or similar authentication and provide automatic IP configuration etc. This allows standard Ethernet to have point to point protocol (essentially 'dial up') style connections supported over a standard Ethernet network with its normal features such as VLAN support etc. It's an encapsulation protocol that takes standard Ethernet frames and put PPP encapsulation inside them. PPPoE is Point to Point Protocol over Ethernet. Thank you everyone for those great suggestions.Ĭould anyone speculate as to why Apple servers reject PPPoE connections?
